If you want to use a private key that you named differently, you have to add it manually: ssh-add ~/.ssh/_id_rsaĪfter entering the passphrase you can check if the key was added to ssh-agent (SSH client) by executing ssh-add -l. ~/.ssh/_id_rsa)? SSH client will not be able to determine where the private key is stored. If you enter the correct passphrase and if that private key indeed is the one which corresponds to the public key which you attached to your profile, all will go fine and the repository will be cloned successfully.īut what if you named your key differently (ex. If that key is passworded (as it should be), you will be prompted for a password, like so: Enter passphrase for key '/Users/steve/.ssh/id_rsa': If you have some private key stored in file ~/.ssh/id_rsa, SSH client will use that private key for communication encryption. Please make sure you have the correct access rights If there is no file in that location, you will get an error: Cloning into 'raspberry-spy'.įatal: Could not read from remote repository. Since we have no clue which private key should be used when SSH-ing into SSH client tries to find a key in default location, which is ~/.ssh/id_rsa - it’s his best guess. You have added the public key to your profile on GitHub, but SSH has to somehow figure out where your corresponding private key is located. To start your work, you have to clone a git repository using SSH: git clone this moment GitHub will be like: “Yo, this a private repository! We need to encrypt traffic using this public key I have here and your private key.” I have also assumed that your name is Steve and you are working on a top-secret project which uses Raspberry Pies to sniff network traffic. I will not go over that step, it should be easy enough to find out how to do that. To do so, you first have to add your public key to GitHub. Let us imagine that you want to push/pull code changes to/from a remote Git server – say GitHub, why not. You have one private key stored in ~/.ssh/id_rsa with a corresponding public key ~/.ssh/id_rsa.pub. Strap in, here we go! Dealing with one SSH keyįirst, let us see what your workflow might look like before having multiple keys to worry about. That being said, there are some Git-specific tricks included. Of course, all of this will apply to any other SSH communication. Most examples throughout the article will be using Git. I assume the reader has basic knowledge of Git and SSH. I hope this article will be of help to anyone who is having issues with SSH key management. Managing SSH keys can become cumbersome as soon as you need to use a second key. You might even be using a different key for accessing your own private server. You might be using one SSH key-pair for working on your company’s internal projects but you might be using a different key for accessing some corporate client’s servers. You use SSH for connecting to remote servers, which also includes managing your code using Git and syncing with remote repositories.Įven though it is considered a good practice to have one private-public key pair per device, sometimes you need to use multiple keys and/or you have unorthodox key names. SSH is one of the most used protocols for safe data exchange. It is safe to say that most developers in the web sphere have at some point encountered SSH.
